Husband was a full-year resident of Illinois and wife was a part year resident (3 month) of Illinois in 2025. We file jointly for our federal return. However, the residence information entered in the Personal section of Turbo Tax did not carryover correctly to the Illinois return. In the Illinois section, the form only allows entry of either the husband or the spouse's residency information-not both. As a result, the Illinois return is showing both taxpayers as either full year resident or part-year residents, which is incorrect.

Please advise on how to properly reflect different residency statuses for each spouse and resolve this issue in Turbotax. Thanks!

For Illinois, if you file a joint Illinois return and one spouse is a full-year resident, both spouses must be treated as full-year residents. This means your wife's worldwide income for the entire year would be subject to Illinois tax. If you want your wife to be taxed only as a part-year resident, Illinois allows you to file as Married Filing Separately (MFS) for the state return even if you file jointly for Federal. Filing Status - IL-1040, Individual Income Tax Return
